Discuss change plastic light switches to metal ones in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
not through conduit and as i said only 2 red wires cant send pic not at houseCan you see how the cables enter the back box is it through steel conduit, is it possible to show a clear pic.
so basically stick with plastic or get an earth wire brought into each light switch?If they are steel back boxes then they have problems all insulated light switch or not.
thanksYes that's right, and with metal boxes in behind I'd check carefully that there's no damage at all to the insulation on the switch cables, make sure connections are properly secure with no copper on show at the terminals and also consider using switches with white plastic screw caps to minimise any risk.
